Stock Pickers No More?

CNBC's website posted a wide ranging article titled Why the Days of Stock Picking May Be Coming to an End. It covered why stock pickers have generally not done well in the last couple of years, why this has helped sector ETFs (and maybe country funds too?), how stock analysts are not political analysts and why that matters and a discussion about passive versus active management.

For part of the article stock pickers was synonymous with active managers. It has been a while since I heard anyone say "it is not a stock market it is a market of stocks" but this entire notion should be dismissed for most market participants. Yes, certain types of fund managers do need to be accountable in three month increments but there aren't too many people whose actual goals are tied to the calendar quarter. If your portfolio owns a couple of stocks that are up a bazillion percent since you bought 25 years ago and/or your yield exceeds your cost basis then you probably don't care that it lagged the SPX this year.

If people perceive that stock picking has become more difficult then it is logical to think that sector funds, country funds and thematic funds have found an audience. At least I hope so. I believe there has always been a middle ground between owning a couple of the broadest indexes via funds and a portfolio with room enough for seven different biotech stocks. ETFs now make it much easier for this middle ground to build a portfolio in this manner.

I think most bottom up stock pickers would say they are not concerned with the macro political environment--a telecom analyst would probably want to keep tabs on big stuff going on at the FCC though, as an example. However top down portfolio managers do keep tabs on political goings on and while no one may get them all correct it usually is part of the process.

Active versus passive is always a worthwhile discussion but usually incomplete IMO. To make the discussion complete it needs to include the appropriate time horizon and risk adjusted results. Specifically these things need to align between manager and client. Generically speaking, getting 80% of the market's return with 50% of the market's risk or volatility (however you want to think about it) is a fantastic result as long as you know that is what your manager is trying to do and understand what your manager is trying to do. If you must be up 15% in an up 10% world, that is not what your manager is trying to do and you don't know it then there will be serious disappointment.

Good post. It is interesting that most investors would agree that risk adjusted returns are how one should "invest" but for some reason most people do not continue beyond stating this point. How do you measure risk? What are you measuring it against? I think the average investor gets lost just about at this point.

Most people don't have the statistical background to use mean-variance measures as a risk measurement tool. They do not understand how negative correlation between one asset to another can result in the inclusion of a high variance (risk) asset in a portfolio while reducing the overall portfolio risk. Or how including some portion of a risk free asset in a portfolio effects risk/return measures.

Furthermore, the average investor is incapable of reading and understanding the average companies financial statements. They are unable to distinguish between GAAP and non GAAP measures of performance when they appear in company press releases. Even those who understand the basics of financial accounting get lost when a company has a pension plan.

No, most investors do not have the technical knowledge, or the time, to analyze individual equity issues (neither do most professionals who sell these securities, which is why they often rely on in house or third party research). As a result, it is by and large foolish for most investors to purchase individual stocks. Though it sure does not seem to stop them and they are often certain that they can "beat the market"
